The street number of Dior’s flagship store at 30 Avenue Montaigne is 30. The address is not a nickname or a reference to a district: 30 is the building number on Paris’s Avenue Montaigne.
Christian Dior established his couture house at the address in December 1946 with financial backing from textile industrialist Marcel Boussac. Dior presented his first collection there on 12 February 1947, and the house’s headquarters and salons became closely identified with the location. The address consequently became one of the most recognizable in fashion history.
A common mix-up is confusing 30 Avenue Montaigne with Dior’s first London boutique at 9 Conduit Street, opened in 1954. Another neighbouring fact readers often ask about is the building’s modern transformation: Dior reopened the renovated site to the public in 2022 after a major project led by architect Peter Marino. The historic address still anchors the House of Dior’s identity.
